Dorsal lunate dislocation and en bloc proximal row carpectomy: a case report

An unhelmeted 59-year-old male involved in a motorcycle accident presented with a right dorsal lunate dislocation in the context of a polytrauma evaluation. Soft-tissue attachments were minimal across the carpus, which allowed for an en bloc proximal row carpectomy. Two-year follow-up yielded a satisfactory outcome given the high energy injury mechanism. Proximal row carpectomy is a useful tool which preserves wrist range of motion in the acute trauma setting and is durable, as demonstrated by our patient's postoperative mobilization using a wheelchair.
